| FFF Compatibility | The physical 48-TSOP package dimensions and pinout match the original MX29LV160DBTI-70G exactly.Standard TSOP-48 package with identical 12mm x 20mm body size and lead pitch.Both devices are 16Mbit (2M x 8 / 1M x 16) parallel NOR flash with bottom boot architecture and 70ns access speed. | The package and pinout assignments match the original part exactly.Standard TSOP-48 package with identical physical dimensions and mounting footprint.The boot block configuration is Top Boot (T) instead of Bottom Boot (B), which requires firmware modification. | ||
 AI Summary | MX29LV160DBTI-70G by Macronix: FLASH - NOR Memory IC 16Mbit Parallel 70 ns 48-TSOP. | This is a direct, fully compatible drop-in second-source replacement from Infineon (formerly Spansion/Cypress). It matches the electrical characteristics, bottom-boot sector layout, and support for both x8 and x16 word configurations. However, please note that this part is nearing its end-of-life status (with a last-time buy set for March 2026).
| This is a sibling variant within the same Macronix family, offering long-term active support and identical electrical parameters. Because this model utilizes a Top Boot sector architecture instead of Bottom Boot, any hardware or system bootloader logic hardcoded to the bottom sectors will require a firmware update to function correctly.
